Specification of Letters Patent.

Patented July'2 2, 191a,

Application filed September 16, 1912. Serial No. 720,547.

To all whom it may concern Be it known that I, BERNHARD Bonasorinn, merchant, a subject of the Emperor of Austriadiungary, resident of Vienna, in the Empire of Austria-Hungary, (whose postletters of reference indicate corresponding parts.

This invention relates to an improvement in devices for the making or preparation of coffee, tea, or the like, consisting of three separate compartments fitting hermetically into one another and superposed one above the other, the lowest being a water-compartment, the second containing the ground coffee, tea, or the like substance, and the third serving as a collector. Into the watercompartment are lodged a number of as cending-tubes 'one or more of which terminate in the second-compartment, while the remainder run right through, terminating finally in the collector. At the lower ends these last-mentioned tubes are surrounded by a bowl-shaped receptacle the object of which is to retain or hold back the liquid until such time when the level of the liquid has attained the height desired in the water-compartment.

The peculiar advantage of this device above those hitherto in use, consists in the fact that, in consequence of the liquid passunder the necessity mg repeatedly through the coitee, tea, or the like substance, this last is completely lixiviated and used up, making it possible to produce a proportionately large quantity of the beverage desired without being drawing it oh". Furthermore,a device is provided, which makes it possible to vary the quantity of the liquid destined to pass through the compartment containing the coffee, tea, or like substance.

This device consists in the peculiar arrangement of the ascending tube or tubes which run from right up into the collector, and which permits of their being adjusted in an altitudinal direction.

An embodiment of the improved device is illustrated by way of example in the accompanying drawing, which shows. a vertical section of the same,

the three ascending tubes,

the water-compartment and wherein -ais the water compartment and b the compartment containing the substance to be lixiviated,'the two being superposed one above the other. These two compartments are separated from each other by a sievebottom -0- slightly below which there is a solid bottom cZ-. Compartment -'b is joined at its top by the collector f-- these two being again separated by a sievebottom g-, the collector itself being closed by a lid of the compartments as of the bottoms, must be hermetically sealed to prevent the escape of steam or the leaking of the liquid.

The device is fitted out with three ascend ing-tubes -i and -j-. The ascendingtube *2' extends from the water-compartment --a right up to almost. close to the lid -hof the collector having at each of its terminations an ingress an.

egressopening 4c, respectively, -Z-.

In order to permit the beverage to be drawn off, a spout -r-' is provided, which may be closed by means of a valve --s-.

In order to prepare the tea, coffee, or the like, the compartment -ais supplied with water, whereupon it is heated. The steam produced, forces the water up through so that a small proportion of the water enters, by means of tube 2'- and the apertures Z and straight into the collector, while the main portion of the water is forced through tubes --jinto the compartment b, where it already partially effects the work of lixiviating the coffee, tea, or like substance, after which it likewise ascends into the collector f-. This process lasts for such a length of time, until the water level sinks below the apertures -7cof tube i. When the Water has attained this -h-. All the joints both in through tube z'.

the level of the liquid has again attained of compartment -buniformly and equally.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is: l 1. In a device for making coffee and the 1 like, in combination, a liquid compartment, a compartment adapted to contain the material to be treated, a collector, a tube communicating with said second compartment 7r: of tube z into the compartment --f thereby causing an equalization of the pressure between this compartment and the Water-compartment a. As aresult the liquid contained in the upper part of the device may descend again, which it does, and after once again lixiviating the substance contained in compartment 6, finally returns into compartment -a by means of tubes -j. The return of the liquid causes the Water-level to rise to the brim of the bowl m,='or, it its sides are provided with apertures t, up to the height of these. By these means the bowl is rc-fillod and the apertures /c are cov- I ered up, so that the steam ceases to flow I This action of the apparatus shows that the bowl m has for its purpose to bring about an intermittent flow of liquid into a, inasmuch as the liquid passing down through the tubes j is prevented from reaching the openings in until level, steam enters through the apertures i tending into sa'idliquid compartment, said each of its ends, and a bowl positioned within said liquid compartment and within which the end of said second mentioned tube terminates.

2. In a device for making coffee and the like, in combination, a liquid compartment, a compartment adapted to contain the material to be treated, a collector, a tube communicating with said second compartment and With said liquid compartment, a tube communicating with said collector and extending into said liquid compartment, said tube being provided with an opening in each of its ends, and a bowl positioned within said liquid compartment and within Which the end of said second mentioned tube terminates, said second mentioned tube and said bowl being adjustable.

In testimony whereof I have aiiixed my the height of the openings t. Only at this point is the passage of steam into'the collector and the back flow of the liquid consequently interrupted.

In order to vary the quantity of the liquid which is to be forced through the compartment b' an adjuster is provided for tube 2'. That is, the higher the apertures /care placed above the bottom or" compartment a-, the sooner the steam begins to enter into the collector, and the liquid to return; whereby it follows that the strlength of the beverage may be varied at wi l.

The object of the bottom d is to enable the Water to cover the whole surface ARTHUR LINDENSTEAD, AUGUST FUGGER.

and with said liquid compartment, a tube communicating with said collector and eX- tube-being provided With an opening in signature to the foregoing specification
